Extraordinary behavior disorders in cows in proximity to
transmission stations.

In addition to reduction of milk yield and increased health problems,
behavioral abnormalities were observed over a period of two years in a
herd of diary cows maintained in close proximity to a TV and cell phone
transmitting antenna.

Evaluation of possible factors which could explain
the abnormalities in the live stock did not disclose any factors other
than the high-frequency electromagnetic fields. An experiment in which a
cow with abnormal behavior was brought to a stable 20 km away from the
antenna resulted in a complete normalization of the cow within five days,
whereas symptoms returned when the cow was brought back to the stable
nearby the antenna.

In view of the previous described effects of
electromagnetic fields, it might be possible that the observed
abnormalities in cows are related to electromagnetic field exposure.
